SD-WAN rule Maximize Bandwidth load balancing algorithm

[igershuni]

Hi everyone!

Does anybody know how to select the load balancing algorithm for Maximize Bandwidth (SLA) SD-WAN rule? If I use SD-WAN with only Implicit "Source IP" rule clients are distributing among WAN interfaces and each client persists its own interface binding while the interface is up. But when I add an SLA rule with Maximize Bandwidth strategy clients become to change WAN interface for each session and this behaviour cause problem with many application (Banking etc.). Is it a bug or design intend? The doc says: "Maximize Bandwidth (SLA) (load-balance): Traffic is distributed among all available links based on the selected load balancing algorithm.", but I do not understand clearly how to select it. The goal is to make traffic distributes among all WAN interfaces that conform to SLA, but clients should persist external IP  as long as corresponding WAN interface is SLA-conformed.

Any help will be very appreciated, thank you!

We are using FG-80E and FG-100F v6.2.2 and here is a suggested config example:

config system virtual-wan-link     set status enable     config members         edit 1             set interface "wan1"             set gateway xx.xx.xx.xx         next         edit 2             set interface "wan2"             set gateway yx.yx.yx.yx         next     end     config health-check         edit "Connectivity_to_Google"             set server "8.8.8.8"             set interval 500             set update-cascade-interface disable             set update-static-route disable             set sla-fail-log-period 30             set sla-pass-log-period 60             set members 1 2             config sla                 edit 1                     set latency-threshold 200                     set jitter-threshold 50                     set packetloss-threshold 5                 next             end         next     end     config service         edit 1             set name "GeneralInternetAccess"             set mode load-balance             set dst "All External"             set src "all"             config sla                 edit "Connectivity_to_Google"                     set id 1                 next             end             set priority-members 1 2         next     end end
